Microarray analysis can provide quantitative gene expression information allowing for the generation of a molecular signature, each unique to a particular class of tumor.

Importantly, the vast majority of tumors identified as high risk by molecular signature.

When embryos are compressed or deformed, asymmetric spindles still form, and staining for gamma tubulin reveals that the second microtubule organizing center lacks the molecular signature of a centrosome.

The presence of these molecular signatures supports their close relationship.

This has led to the development of molecular signatures for prediction of cancer risk and adverse effects.
